MECHANICAL MOVEMENT.

Application filed January 20, 1913.

To all whom it may concern:

Be it known that 1, ANDREW E. MILLER, a citizen of the United States, residing at Louisville, in the county of Winston and State of Mississippi, have invented a new and useful Mechanical Movement, of which the following is a specification.

One object of the present invention is to provide a spring motor of novel and improved form adapted to be employed for actuating the movable element of a churn.

\Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of in vention can be made within the scope of what is claimed without departing from the spirit of the invention. In the drawing :Figure 1 shows the invention in side elevation; Fig. 2 is an end elevation; Fig. 3 is a vertical longitudinal section; Fig. 1 is an elevation of the cam wheel; and Fig. 5 is a transverse section on the line 55 of Fig. l.

In carrying out the invention there is provided a supporting structure comprising a base 1. Fixed to and upstanding from the base 1 is a U-shaped frame 2, sustained by means of a brace 3. For the sake of compactness, the frame 2 may be contracted in termediate its upper and lower ends as indicated at 4.

Journaled for rotation in the frame 2 is a winding shaft 5 to which is secured one end of a coil spring 6, the other end of which is secured to a drum 7, provided with outstanding handles 8, the drum 7 being secured to a ratchet wheel 9 having a collar 10 which is journaled on the winding shaft 5 to one side of the frame 2. A pawl 11 is pivoted to the frame 2 and is sustained by a spring 12 to engage the ratchet wheel 9.

Secured to the winding shaft 5 and located between the side portions of the frame 2 is a pinion 14 which meshes into a pinion 15 secured to a shaft 16 journaled in the frame 2. The shaft 16 carries a pinion 17 meshing into a pinion 18 secured to a shaft 19 journaled in the frame 1 above the shaft 16.

Secured to one end of the shaft 19 and located to one side of the frame 2 is a wheel Specification of Letters Patent.

Serial No. 743,176.

A weight 28 is slidable upon the lever 21 between the fulcrum 25 and the cam wheel 20, the weight 28 being held in adjusted positions along the lever by means of a set screw 29. The outer end of the lever 2-1 is loosely connected as indicated at 30 with a dasher rod 31 mounted to reciprocate in a receptacle 32 which is supported by the base 1. The dasher rod 31 reciprocates in a lid 33 which rests upon the top of the re ceptacle 32. Located above the lid 33 and surrounding the dasher rod 31 is a ring 34:, and a frusto-conical cover 35 which may be fashioned from netting, contacts the ring 31 with the periphery of the lid 33. Located between the depending flange of the lid 33 and the body portion of the receptacle 32 is a coiled spring 36, one end of which is secured as indicated at 37 to the lid 33. The spring 36 surrounds and embraces closely, the neck of the receptacle 32.

Projecting from the frame 2 is an arm 33 to which is secured an overhanging support 39. Secured to the lower edge of the arm 38 and alined vertically with the end of the support 39 is a bracket 40. Screws 4Z1 are threaded intothe support 39 and into the bracket 40, the screws receiving for rotation a worm 42 which meshes into a wheel 13 secured toa shaft 44 journaled in the arms 38. Secured to the worm 4:2 to rotate therewith is a yoke 45 upon which is pivoted a pair of counter-weighted arms 46 having approaching angularly protruding extensions 47 adapted to bear upon the upper end of a spool 48 which is journaled upon the worm 42 above the threaded portion thereof. The spool 18 rests upon one end of a lever 49 which is fulcrumed as indicated at 50 upon one of the arms 38, and is adjusted by means of a screw 49* threaded into a oleat 19* on the arm 38. 7

All of the shafts and pinions hereinbefore described may be retained in proper relation with respect to the frame 2 by means of collars 51 held in place by set screws" 52, the construction being such that any part may be removed readily for renewal or for repair.

The moving parts of the structure may be housed within a casing 53 of any sort, supported by the frame 2.

The actuating spring 6 may be put under tension by rotating the drum '7 and the ratchet wheel 9 through the medium of the handles 8, the back stop pawl 11 exercising its obvious function. The spring 6, when under tension, will drive the shaft 5, the pinion lat meshing into the pinion 15 and actuating the shaft 16. The pinion 17 on the shaft 16 will drive the pinion 18, the pinion 18 rotating the shaft 19 and the shaft 19 rotating the cam wheel 20. hen the cam wheel 20 is rotated, one end of the lever 21- will ride in the cam groove 21, and owing to the peculiar construction of the cam groove, as clearly outlined in Fig. 4:, two strokes will be imparted tothe lever 21 at each rotation of the cam wheel 20. l/Vhen the lever 21 is reciprocated, vertical reciprocatory motion will be imparted to the dasher 31 which is mounted to operate within the churn receptacle 32. At this point it may be noted that since the lid 33 of the receptacle is provided with the contractile coil, spring 36,v the lid may be assembled readily with receptacles of difierent diameters. When the shaft 16 and the pinion 17 are rotated,vthe pinion 17, meshing into the pinion 14, will actuate the worm 452. When the worm 12 is rotated, the counter-weighted arms 16 will fly outwardly, the extensions 17 bearing upon the upper end of the rotatably mounted spool 48 and thrusting the: spool 18 downwardly upon the upper end of the lever 49. Since the lever 19 is mounted to swing, as indicated at 50, a brake pressure will be applied to the spool 4-8- and to the Worm 4:12, the speed being thereby held back. Owing to the fact that the lever 49 is adjustably supported at 49", the brake pressure may be regulated readily. The speed with which the worm 12 rotates may be limited further by adjusting the pressure with which the screws 11 bear against the ends of the worm.

As will be understood readily, the set screw 29 may be loosened. permitting the .weight 28 to be shifted along the lever 24.

Owing to the provision of the Weight 28, the lever 24 may be counter-balanced, to off-set the weight of the dasher rod 31. V

Having thus described the invention, what is claimed is 1- In a device of the class described, a frame; a wheel journaled on the frame and provided with a cam groove in its side face; means for driving the wheel a lever disposed substantially at right angles to the groove-carrying side face of the wheel, one end of the lever being received in V the groove; a pivot element connecting the lever intermediate its ends with the frame; a driven. element carried by the outer end of the lever and supported solely by the lever; aweight mounted for sliding adjustment on the lever between the pivot element and the wheel; and means for securing the weight in adjust-ed positions on the lever; the weght being adjustable to counteract the weight of the driven element and to hold the lever between the groove-received end of the lever and the wheel, the disposition of the lever at right angles to the wheel permitting the weight to be held close to the wheel, thereby giving the weight a maximum moment.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
